Adaptive Hybrid Transmission Mechanism for Free Space Optical Communication Network

In this paper, we propose an Adaptive Hybrid Transmission schemes for free space optical communication. Proposed algorithm utilizes hybrid mechanism which combines Multi-channel multicasting and unicast scheme to enhance not only service over service blocking probability but also reduce overall bandwidth consumption of the free space optical communication system which has very limited resources compared to optical fiber communication. An adaptive resource allocation algorithm is also proposed and is shown to achieve minimum blocking probability. In order to evaluate the performance we compare proposed algorithm against traditional unicast and multicast schemes.
